Marchand peppered his teammate with questions identical to what fans and media were wondering.

Was Bergeron OK? What happened to him? Will he be able to play in Game 6?

And also: Was Bergeron’s season done?

“We wanted to get updated,” Marchand said. “Obviously at a point like this, you’re worried about a guy, especially your top player.”

On Sunday, coach Claude Julien offered an update — Bergeron is “day-to-day” with a “body injury,” no clarity on where the 27-year-old is ailing.

And no indication if Bergeron, a clutch scorer and the team’s top faceoff man, will skate at practice on Monday morning.

Bergeron played only 49 seconds in the second period Saturday. On his last shift he halted awkwardly by the boards, straightened up, then scooted off the ice.

The Bruins face the Blackhawks Monday night at TD Garden. The Stanley Cup will be present. Chicago leads, 3-2, in the best-of-seven series.

Julien was both cautious and indefinite when discussing Bergeron.

“What does day-to-day mean?” Julien said. “I don’t know . . . I’m trying to be as clear as I can here.”

Julien later added: “Day-to-day is really good news to me anyways.”

The Bruins who spoke Sunday were dressed in black. Marchand wore a polo shirt and dress pants. Goalie Tuukka Rask and forward Nathan Horton had similar attire.

And when they spoke of Bergeron, the alternate captain with nine goals and six assists these playoffs, their voices lowered.

“He plays in every situation, power play, and penalty kill,” Rask said. “So it would be a huge loss for us . . . But then again we can’t be feeling sorry for ourselves.”

Bergeron traveled with the team back to Boston. What was the mood on the flight?

“It was about a two-hour flight,” Marchand deadpanned. “No layover. We played some cards.”

Bergeron attended the team meal at the hotel on Saturday night. He “crushed down some food,” according to Marchand, including some french fries.

“He was wearing a suit,” Marchand said. “Very dashing.”

If Bergeron cannot play, Julien must improvise.

Swedish forward Carl Soderberg made his postseason debut Saturday as a fourth-line wing. He was promoted to second-line center after Bergeron left in the second period.

“[Soderberg] went out there and played hard,” Julien said. “I didn’t mind his game.”

Soderberg might find himself back on the second line Monday. Or perhaps Julien will call upon another reserve forward, or even dress a seventh defenseman.

“If it’s not Bergy, I’m going to look, is [Soderberg] the right fit?” Julien said. “Or do I look for something else? And I may have to juggle some players around, but that will happen more [Monday] when we find out more.”

Soderberg said he did not know Bergeron’s status but repeatedly said he hopes the forward can play “because that is what is best for the team.”

During Game 5, Soderberg said there was an air of uncertainty on the bench. The players were instructed to focus on the ice.

“You’re just focusing on your own game,” Soderberg said. “We saw he was injured. We don’t know what happened to him.”
